Monitoring relay for monitoring 1-phase voltages of 0…300 V AC/DC, overvoltage/undervoltage or window, error memory, wide range power supply unit, 2 changeover contacts
Monitoring relays are an inexpensive solution for monitoring important electrical and physical system parameters. EMD monitoring relays can be used to monitor overvoltage, undervoltage, overcurrent, undercurrent, phase failure, phase sequence, phase asymmetry, power factor, active power, motor winding temperature, and fill levels. The current relay detects and monitors sinusoidal alternating currents in the frequency range from 45 to 65 Hz.More information
Ideal for series production: the EMD-BL compact monitoring relays are a price-optimized solution for numerous monitoring functions. Use the compact monitoring relays to monitor important system parameters in your application. Detect critical errors at an early stage, report them, and shut down system parts selectively.
Your advantages with our compact monitoring relays
Use the EMD series to monitor electrical as well as physical system parameters. The multifunctional monitoring relays offer a wide range of monitoring functions. In addition, extended setting options and variable supply voltage ranges make the devices particularly versatile.
Your advantages with our multifunctional monitoring relays
The current relay converts sinusoidal 50 Hz/60 Hz alternating currents into binary switching signals. Current detection takes place inductively via the conductor led through the module. The switching thresholds are set roughly via internal DIP switches, with fine adjustment performed using a potentiometer on the front. A high-quality changeover contact relay with a gold layer is located on the output side. It can be operated in both open and closed circuit current behavior.
